Texas Instruments datasheet for the SN74LVT162244DLR, a 16-bit 3.3 V buffer and line driver with three-state outputs and series output resistors, indicated by the 162 prefix. It comes in an SSOP package marked DL and is supplied on tape and reel, hence the R. The 25.9 KB file is a compact product sheet. It helps you identify the four output-enable groups when you trace address buses or memory interfaces. Check every enable line before condemning the chip, since one disabled group can mimic a dead device.
